1. A device, comprising:
- a magnetic resonance tomograph (MR); and
a positron emission tomograph (PET) including avalanche photodiodes as reception elements of the PET, and including Peltier elements to cool the avalanche photodiodes;
a temperature sensor in conjunction with a control instrument to regulate a temperature of the avalanche photodiodes; and
two Peltier elements arranged with their hot sides facing each other, wherein a cooling instrument is provided between the two Peltier elements, while the avalanche photodiodes and the PET electronics are respectively arranged on the cold sides of the two Peltier elements.

Abstract
At least one embodiment is directed to a combination of an MR tomograph and a positron emission tomograph having avalanche photodiodes as reception elements. In at least one embodiment, the intention is to ensure that the avalanche photodiodes are kept at a constant temperature despite the exposure to heat from the MR components. It is proposed, in at least one embodiment, that cooling by Peltier elements 5 should be provided.
